ABSTRACT
This study identified the subtypes of psychosocial functioning in children who had sustained traumatic brain injury using the Behavior Assessment System for Children, Second Edition. Participants (N = 91) were aged 6-20. Using hierarchical agglomerative clustering techniques, a reliable typology emerged that consisted of two subtypes, which were labeled as Normal and Pervasive Emotional Difficulties. Using further exploratory analyses, other less statistically reliable subtypes were also observed, which were thought to have clinical significance. These were labeled as Mild Externalizing/Depression, Mild Externalizing/Attention Problems, Mild Depression, and Mild Anxiety. The majority of participants were assigned to the Normal subtype. Relationships between subtypes and other variables, including gender, time elapsed since injury, age at injury, and age at testing were also analyzed, with time elapsed since injury being the only variable to significantly differentiate the subtypes.
